FORGlNG-PR-ESS.

SPECIFIGATION forming part of Letters Patent NO. 678,291, dated July 9, 1901. Application filed February 16, 1901. Serial No. 47,641. (NomodelJ To all whom it may concern:

Be it known that I, ELMER P. ALEXANDER,

a citizen of the United States, residing at Yeagertown, in the county of Mifflin and State of Pennsylvania, have invented a new and useful Forging-Press, of which the following is a specification.

My invention is an improvement in forgingpresses for forging axes and the like, and relates more particularly to the drop-base, the object of the invention being to effect improvements in the construction of the dropbase and its combination with the standards, whereby the drop-base forms the sole support for the lower die-block, the header-arm, and the standards between which the drop that carries the upper die-block is guided and whereby the drop-base is provided with an integral enlarged portion adapted to receive the stress of the header block and arm to form a seat for the standards and to entirely relieve the latter of the stress occasioned by the forging.

My invention consists in the peculiar con struction and combination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a forging-press constructed in accordance with my invention. Fig. 2 is partly a top plan View and partly a horizontal sectional view of the same, taken on a plane indicated by the line A A of Fig. 1. Fig. 3 is a vertical longitudinal sectional View of the same, taken on a plane indicated by the line B B of Fig. 2. Fig. 4 is a detail perspective view of the drop-base.

In the embodiment of my invention the drop-base l is made of a single piece of cast metal, preferably steel or iron. Across the upper portion of the drop-base, near the center thereof, is formed a seat 2 for the lower die-block 3. A transverse dovetailed groove 4, open on its upper side, is cut in the dropbase for the correspondingly-shaped lower portion of the lower die-block and for the key 5, which secures the lower die-block in its seat. One end'of the drop-base is enlarged longitudinally and vertically, the said enlarged portion 6 being formed integrally with the drop-base and extending above the seat 2 for the lower die-block for a suitable dis- In the said enlargement 6 is out a tance.

longitudinal seat 7 for the headerarm 8-, which at its inner end carries the headerblock 9, which coacts with the lower and upper die-blocks in the formation of the heads of the axes and which receives the stress occasionedby the forging of the heads of the axes, the said stress communicating an outward thrust to the header-arm 8. At the outer end of the seat '7, in which the header-arm is disposed, is inserted a wedge-shaped key 10, which bears against the outer end of the header-arm. Shims, one or more, of the requisite thickness may be also seatedin the outer end of the header-arm seat 7 to effect in connection with the key 10 the requisite adjustment of the header-block in the die. It

willbe understood that the stress occasioned by the outward thrust of theheader-arm when the axes are forged is entirely borne by the enlarged integral portion 6 of the drop-base. That portion 11 of the drop-base which forms the outer end of the seat 7 for the header-arm is strengthened by the integral longitudinallydisposed portions 12, which form the sides of said seat. It will be understood that each outward thrust of the header-arm when an ax is forged is followed by a rebound thereof. In order to prevent the header-block 9 from becoming displaced in the die and to keep the outer end of the header-arm in contact with the key at the outer end of the seat 7, I provide'a spring 13, which at one end is secured to the'shoulder or wall formed by the face of theenlarged portion 6 proximate to the seat 2 forthe lower die-block. The free end of the said spring bears against the inner end of the header-arm below the header-block, and said spring,as hereinbefore indicated, keeps the header-block and header-arm normally disposed in the required positions thereof and counteracts any tendency of the rebound of the header-arm and header-block to displace the latter in the die. The upper die-block 14: is carried by the drop 15, which, as is usual in forge-presses, is guided by the vertical standards 16. A seat 17 is formed in the enlarged portion 6 of the drop-base for the base of one of the standards 16, the latter having an opening 18 therein, through which the header-arm 8 extends. The seat 19 for the base of the other standard is a plane surface, which is level with the lower side of the seat 17. As

here shown, the standards are secured to the drop-base by dowel rods or bars 20. It will be understood, however, that bolts may be employed in lieu of the dowels to secure the standards to the drop-base.

It will be understood from the foregoing and observed by reference to the drawings that the standard, which is disposed opposite the head end of the die, is firmly seated in the enlarged integral portion of the dropbase, so that the said standard cannot become displaced. Moreover, as the said standard has an opening through which the header arm extends and as the latter is also firmly seated in the enlarged integral portion of the drop-base the said standard is entirely unaffected by the thrusts of the header-block and header-arm and is not subjected to stress oc casioncd thereby. Inasmuch as the dropbase, provided with the seats for the lower die-block, header-arm, and standard, is an integral casting, the same is of maximum strength, is very durable, and is not likely to be broken.

Having thus described my invention, I claim- 1. A drop-base for a forgepress having a seat for the lower die-block and a seat for the header-arm, the latter being contained within the said seat, whereby the stress occasioned by the thrust of the header-arm is borne by an integral portion of the drop-base at the outer end of the said header-arm, substantially as described.

2. A drop-base for a forge-press, having a seat for the lower die-block, a seat for the header-arm and a seat for the base of the guide-standard proximate to the seat for the lower die-block, substantially as described.

3. In a forge-press, a drop-base having a seat for the lower die-block, a seat for the header-arm, and a seat for the lower end or base of the guide-standard, disposed opposite the head of the die, in combination with the said standard and the header-arm, said standard having an opening through which said header-arm extends, for the purpose set forth, substantially as described.

4. A drop-base for a forge-press, having an integral enlargement at one end, the said enlargement being provided with a seat for the header-arm and extending beyond the outer end of said header-arm, for the purpose set forth, substantially as described.

5. In a forge-press, the combination of a drop-base having a seat for the header-arm and a seat for the lower die-block, the headerarm in said header-arm seat and a spring bearing against the inner end of the said header-arm, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

E. P. ALEXANDER.
